Geo-engineering trial aims to store winter temperatures in a giant block of ice that will cool and water Ulan Bator in summer. Guardian Online: Mongolia bids to keep city cool with ice shield experiment | Environment | guardian.co.uk.
Well, my feelings about this are in the comments following the article, but while the natural engineering involved in “making a naled” is impressive, I don’t believe a £500K Anglo-Mongolian joint venture is going to be able to replicate it, and don’t really believe it should try.
Even if it works, drilling into a nearly dry river could lock up already scarce water supplies from spring through autumn. How do they see the cooling from this waterway reaching distant neighbourhoods and the vast, under-served ger communities encircling the city? Summers there are not deathly hot (yet) and Ulan Bator residents would be better served by getting better-built buildings without glacial air-conditioning on offer to those who can afford it.
I hate to be a pessimist on this – if it works, yes, it only burns the fossil fuel for the drills and that would be great. But I fear another boondoggle and hope city residents don’t lose out.
